This lnvention relates to certain improvements inpumps and has relation more particularly to a rotary pump wherein is employed a rotor provided with a plurality of substantially radially movable blades; and

it is an object of the invention to provide a pump of this general character having novel and improved means whereby the rotor together with the blades thereof may be operated with a minimum of eccentric friction and at the same time adording a maximum of water space.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved pump whereby certain important advantages are attained and the devlce is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter moreiully set forth.

The novel features of the invention will hereinafter be denitely claimed.

ln order that my invention may be the better understood, I will not proceed to describe the same with reference to the ac companying drawings, wherein- Figure l is a vertical sectional view, with parts in elevation of a ump constructed in accordance with an em odiment of my invention; f

Fig. 2 is a vertical sectional view of the rotor as herein embodied the operating shaft coacting therewith being shown in fragment;

of the discharge pipe 2 through the medium of the coupling 3.

The opposite ends of the casing lA are closed by the heads 4 and 5 and a marginal portion or the upper head4 is cut away, as at 6, to anord a discharge or outlet for the chamber created between the heads 4 and 5. The portion of 'the chamber immediately below the cut-away portion 6 is gradually enlarged2 as indicated at 7, in the same general direction as the directlon of rotation of the rotor R positioned within the chamber between the heads 4 and 5 with the base 8 4of said enlargement disposed on a predetermined incline so that as the rotor R is operated, the blades B coacting with the rotor will serve to lift the water through the discharge k6, said water being received within the casing l between said heads 4 and 5 through the ingress opening 9 suitvably positioned in a sidewall of the casformation of the upper head '4 and said top head 1l of the rotor Ft is keyed or otherwise aiixed to the lower extremity of the operating shaft l2. 'llhe shaft l2 extends upwardly through the discharge pipe 2 and' is adapted to 'be driven in any desired manner in order that the requisite rotation may be imparted to the rotor llt.

The lower head 14 of the rotor R is proi vided with the opening l5 which snugly receivesl the. upstanding portion, lug, or bearing, 16 carried by the lower head 5 of the casing l concentric to theshar't l2 and which affords a mounting tor` the lower end portionof the rotor llt, 'causing the rotor R to become,virtually, an enlarged continuation of the shaft 12 vwith a bearing at either end thereof, the hollow inside of the Arotor R being reserved or used for the operation of the blades B.' v

lnterposedibetween the heads 5 and 14 is an anti-friction means generally indicated at A, and which may be of a construction as may best meet the requirements of practice in order to assure the rotation ofthe rotor R with a of frictional reheads 11 and 14 affords an inclosed chainber C, and disposed longitudinally thereof and at a point eccentric to the axial center of the rotor is the stationary shaft 17 herein disclosed as an elongated member cylindrical in cross sectionand disposed through the lower head 5. Coacting with the lower end of the shaft 17 and the lower head 5 is the clamping nut 18 while the upper end portion of the shaft 17 is provided with the extension 19 substantiall semi-circular in cross section and which is snugly received yvithin a corresponding opening 20 produced ii the plate 21. `The plate 21 is provided with an upstanding lug or stub shaft 22 circular in cross section and which -is disposed within acorresponding recess or socket 23 produced in the lower end of the operating shaft 12 at the axial center thereof. By this arrangement it will be perceived that the plate 21 serves as a rest or supi; rt for the l,upper end portion of the sha y17 and also holds the same against rotation or turning movement as the upstanding lug or stu shaft 22 is eccentric to the opening 20.

The blades B are disposed radially of the .rotor R and extend within the chamber C of said rotor and are also of a length substantially equal to the length of the rotor. In practice I have found it of particular i advantage to have said blades eight in number with the same arranged 4in four self-evident that the airs, the blades of each pair being diametrically opposed and rovided at their rear margins with the longitudinallyspaced arms 24, each pair of alined arms beine nected with an elongat eye 25 through which the shaft I17 extends, saideye being elon .ated with its major axes disposed perpen. icular to the pair of coactin blades B. Asis particularly illustrated in ig. 1 it is to .be noted that adjacent arms 24 and eyes 25 are substantially in contact one with the other, whereby the strength of the eyes is materially increased. 4 It is thought to be osition Aof the shaft 17 and the coaction o the eyes 25 are such as to maintain the blades B constantly in contact with the inner walls ofthe casing 1 whereby it will be obvious that as the rotor R is revolved the uid entering the .casin through the ingressopening 9 will be through the discharge 6.

It is to be noted 4that one pair of. alined arms is arranged adjacent the'longitudinal lcenter of the coacting blades while the second pair of alined arms is arranged adjacent an. end portion 'of the blades. By this arrangement it has beenfully demonstrated that the blades ,B may be materially operatively coiiiifte p longer and that this i particular arran ement of the alined arms 24 serves eifectua y to prevent twisting strain upon the blades relative to the shaft 17.

. While my invention has been hereinbefore set forth in connection with a rotor revolving about a vertical axis, for drilled or deep well pumps, it will be understood that my invention can be employed with equal facility in connection with a pump wherein the rotor revolves about a horizontal axis suited 'to a suction lift`- and discharge elevation by means of pipes attached to the outer casing 1 for ingress and egress of the fluid on opposite sides of the cut olf made by means of the rotor coming in close contact with the outer casing between the ingress and egress pipes attached thereto. As this construction isthought to fairly fall within .my invention as. claimed, a detail description and illustration thereof is believed to be unnecessary. t

From the foregoing description, it is thought to be obvious that a pump constructed in accordance with my invention is of an extremely simple and comparatively vinexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious thatmy invention is susceptible of some'change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as v limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.
